New research provides insight into how an enzyme that helps regulate aging and other metabolic processes accesses our genetic material to modulate gene expression within the cell. A team led by Penn ...

Enzymes are amazing catalysts. These proteins are made of nothing more than a handful of Earth-abundant elements, and they promote a vast array of reactions, convert chemical energy to physical motion ...

The new study reveals a remarkable way that cells keep us safe from transposable elements (TEs) gone wild. The researchers found that cells have taken advantage of an entire protein network to repress ...

You can't have TET proteins activating every gene at the same time. In normal cells, TET protein activity is restricted to the genes that need to be expressed in that particular cell type. In the new ...
